Jarsmaterials
Jarsmaterials refers to the range of materials used to manufacture jars. Common jar materials include glass, plastics such as PET, HDPE and PP, metals like tinplate and aluminum, ceramics, and laminated or composite films. The choice of material influences barrier properties, chemical compatibility, heat tolerance, durability, weight, and recyclability.
Glass jars are widely used for foods and preserves because they are chemically inert, impermeable to gases
Metal jars, usually tinplate or aluminum with protective coatings, provide strong barriers and good heat tolerance,
Material selection also considers process compatibility, including filling temperature, sealing method, and sterilization cycles. Regulatory requirements
Environmental aspects emphasize recyclability and circular use. Glass is highly recyclable with low contamination, while some
